The red supergiant Betelgeuse, a colossal star in the Orion constellation, experienced a massive stellar eruption in 2019, the likes of which have never been seen, according to astronomers. The ...

The huge red supergiant star Betelgeuse blew off a huge chunk of its mass in 2019, creating a cloud of dust which obscured its light and caused it to dim.

These pulsations are typical of red supergiant stars such as Betelgeuse, and their period varies from star to star depending upon the star’s mass. “I believe the intrinsic 416-day pulsation rate is ...

It seems Betelgeuse suffered a massive surface mass ejection (SME) event in 2019, blasting off 400 times as much mass as our Sun does during coronal mass ejections (CMEs).

Sitting on the shoulder of the constellation Orion, Betelgeuse is one of the brightest stars in the sky.In early 2019, however, the massive star underwent a puzzling dimming event that was visible ...

The bright, naked-eye star Betelgeuse is well known for its variations — some of which may be caused by an unseen companion star. ... which makes it a mere one-twentieth the mass of Betelgeuse.

Betelgeuse, one of the biggest and brightest stars in the night sky, ... Scientists expect Betelgeuse to be short-lived, given its mass and the speed at which it's burning through its material.

Betelgeuse experienced a weird cosmic event in 2020 that led to some supernova speculation. It's doing it again — but it's (probably) just settling down.

After millions of years, stars that are between eight and 30 times the sun’s mass evolve into yellow supergiants, spend a few thousand years as such, then become red supergiants like Betelgeuse.

Betelgeuse, Betelgeuse! The red supergiant that marks Orion’s left shoulder may have a tiny, unseen companion. Two independent studies found evidence of a star about the same mass as the sun ...
